> lambda apps

Yes, SST [1] uses lambdas heavily but makes it more seamless and less visible, just the place your code runs.

I’ve also found Azure Container Apps to hit the right balance. It’s kubernetes under the hood, which you don’t have to mess with at all, except that it can use KEDA [2] scaling rules to scale your containers to zero, then scale up with any of the supported KEDA scalers like when a message hits a queue.
